What is the difference between an associate and a sister?

Associates are Christian women and men who formally associate themselves with a religious community, its mission and spirituality. Presentation associates embrace the Presentation vision and mission of hospitality, prayer and service. These women and men share in the life and ministry of the Presentation sisters without seeking vowed membership. Sisters take vows of poverty, celibacy, and obedience, live in community, sharing all finances, and share responsibility for the welfare of the members of their religious community.
